    1. uses the storage capability and physical attributes of phase-change memory (PCM) devices to more efficiently implement an artificial neural network.

      a type of non-volatile random-access memory that exploits the unique properties of phase change materials, typically chalcogenide alloys like Germanium Antimony Tellurium (GST). These materials can be rapidly switched between amorphous and crystalline states by applying heat, usually through electrical pulses

    2. Then, using the two outputs, the original inputs can be recovered in a decomputation step.

      The two steps of reversible computing: 1. Clone one of the inputs along with the output (total 2 outputs) 2. "Decompute" to find the other input (reversing the computation)
